Nanosensor

"Imagine a swing that, once pushed, keeps swinging for almost 100 years because it loses almost no energy through the ropes." So says a Delft University of Technology researcher who has helped his team accomplish a parallel feat at the nanoscale.

Could a nano array that can identify the chemical signatures of diseases bring us closer to the day when doctors might be able to use a medical tricorder a la Star Trek to instantly diagnose a patient’s conditions?

Nanosensors that detect a molecule known as adenosine triphosphate could help reduce the number of laboratory experiments that rely on animals.

Researchers have built nanoscale generators that harvest mechanical energy derived from straining to power tiny sensors.

Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans.
